TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of household appliances and in particular to an appliance structure having functions of both a wall-breaking machine and a slow juicer.

BACKGROUND OF THE INVENTION

A wall-breaking machine can break the cell wall of vegetables and fruits and effectively extract phytochemicals so that nutrient substances are more easily absorbed by the body. The ingredients are almost pasty if the ingredients are processed by a wall-breaking machine, while juice can be extracted from the ingredients if the ingredients are processed by a slow juicer. The juice extracted from the ingredients by a slow juicer may be easily separated from the residue. Juice extracted from the ingredients by a wall-breaking machine and juice extracted from the ingredients by a slow juicer taste different. To meet the demands of family members having different tastes, some families may buy a wall-breaking machine and a slow juicer. Buying both a wall-breaking machine and a slow juicer causes large space occupancy and high cost.

In the present invention, the wall-breaking machine and the slow juicer are integrated. By replacing different cutters and by rotating the first output shaft clockwise or counterclockwise, the wall-breaking function or the juicing function is realized.

Preferably, the second output shaft is sheathed on the first output shaft, and the first output shaft and the second output shaft are arranged coaxially. With such an arrangement, appliances having this structure of the present invention have smaller size and smaller space occupancy.

Preferably, the first output shaft is linked with the second output shaft via a single-stage transmission mechanism; the single-stage transmission mechanism comprises a first gear, a second planetary gear and a second planetary carrier; an outer ring of the one-way bearing is linked with the first gear; the first gear is meshed with the second planetary gear; the second planetary gear is fixed with the second planetary carrier via a second axle; the second planetary carrier is fixed with the second output shaft; and the first gear is formed with a through hole for the first output shaft to pass therethrough.

Preferably, the first output shaft is linked with the second output shaft via a two-stage transmission mechanism; the two-stage transmission mechanism comprises a first gear, a first planetary gear, a first planetary carrier, a second gear, a second planetary gear and a second planetary carrier; an outer ring of the one-way bearing is linked with the first gear; the first gear is meshed with the first planetary gear; the first planetary gear is fixed on a side of the first planetary carrier via a first axle and the second gear is fixed on the other side of the first planetary carrier; the second gear is meshed with the second planetary gear; the second planetary gear is fixed with the second planetary carrier via a second axle; the second planetary carrier is fixed with the second output shaft; the first gear, the first planetary carrier and the second gear are each formed with a through hole for allowing the first output shaft to pass therethrough.

Preferably, the first output shaft is linked with the second output shaft via a three-stage transmission mechanism; the three-stage transmission mechanism comprises a first gear, a first planetary gear, a first planetary carrier, a third gear, a third planetary gear, a third planetary carrier, a second gear, a second planetary gear and a second planetary carrier; an outer ring of the one-way bearing is linked with the first gear; the first gear is meshed with the first planetary gear; the first planetary gear is fixed on a side of the first planetary carrier via a first axle and the third gear is fixed on the other side of the first planetary carrier; the third gear is meshed with the third planetary gear; the third planetary gear is fixed on a side of the third planetary carrier via a third axle and the second gear is fixed on the other side of the third planetary carrier; the second gear is meshed with the second planetary gear; the second planetary gear is fixed with the second planetary carrier via a second axle; the second planetary carrier is fixed with the second output shaft; and the first gear, the first planetary carrier, the third gear, the third planetary carrier and the second gear are each formed with a through hole for allowing the first output shaft to pass therethrough.

A single-stage transmission or a two-stage transmission or a third-stage transmission or the like is selected as desired. The simultaneous rotation of the first output shaft and the second output shaft is realized by a planetary gear transmission mechanism, and the size of appliances having this structure of the present invention is reduced. It is well known that a ring gear may be provided on each of the outer side of the first planetary gear, the outer side of the second planetary gear, and the outer side of the third planetary gear.

Preferably, the outer ring of the one-way bearing is fixed with an inner wall of a bushing which is a ring-shaped structure; the first gear comprises a first gear portion I and a first gear portion II; on an outer wall of the first gear portion I, a threaded structure fitted with an outer wall of the first planetary gear is formed; and the first gear portion II is fixed within the bushing. In such an arrangement, the outer diameter of the first gear portion II is less than the outer diameter of the first in a case where the first gear is directly sheathed outside the one-way bearing. The inner edge of the first gear in the present invention is located on the inner side of the outer ring of the one-way bearing. The first gear may be made smaller so that the distance between the first planetary gear and the first gear becomes smaller. Accordingly, the space occupied by the transmission mechanism is reduced, and thus appliances having this structure of the present invention have a smaller size.

Preferably, an eccentricity-prevention bearing is sheathed on the first output shaft; an inner ring of the eccentricity-prevention bearing is fixed with the first output shaft and an outer ring thereof is linked and fixed with the second output shaft; and the second planetary carrier is formed with an accommodating groove for accommodating the eccentricity-prevention bearing, and the eccentricity-prevention bearing is located within the accommodating groove.

In the present invention, the first output shaft is relatively long. The arrangement of the eccentricity-prevention bearing prevents the eccentricity of an end of the first output shaft during the rotation. The accommodating groove is arranged on the second planetary carrier so that the second output shaft has a small diameter. In this way, the material consumption is reduced and the coordination between the second output shaft and the cutter is facilitated.

Preferably, the second output shaft is fixed with a plurality of fixed bearings; an inner ring of each of the fixed bearings is fixed with the second output shaft and an outer ring thereof is fixed with the housing; one axial end face of a fixed bearing closest to the second planetary carrier comes into contact with an end face of the second planetary carrier and the other axial end face thereof comes into contact with a circlip for holes, and a first annular groove or a first arc-shaped groove is formed on the housing to fit the circlip for holes; or the other axial end face of a fixed bearing closest to the second planetary carrier comes into contact with a circlip for shafts, and a first annular groove or a first arc-shaped groove is formed on the second output shaft to fit the circlip for shafts. Such an arrangement is designed for the fixation of the second output shaft. When there is only one fixed bearing, an end of the fixed bearing comes into contact with the second planetary carrier and the other end thereof is limited by the circlip for shafts. When there are at least two fixed bearings, a fixed bearing closest to the driving motor is limited by the circlip for holes and the second planetary carrier.

Preferably, the second planetary carrier and the second output shaft are integrally molded. Such an arrangement is convenient for the assembly of the present invention and makes the rotation of the second output shaft more stable.

Preferably, an end of the first output shaft away from the driving motor is a first fixed end, and an end of the second output shaft away from the driving motor is a second fixed end; and the first fixed end extends beyond the second output shaft. Such an arrangement is convenient for the assembly of the first output shaft with the cutter and also the assembly of the second output shaft with the cutter.

In the present invention, the wall-breaking machine and the slow juicer are integrated. By replacing different cutters and by rotating the first output shaft clockwise or counterclockwise, the wall-breaking function or the juicing function is realized. Furthermore, the present invention also has the advantages of smaller size and smaller space occupancy.
